T all wiz/'omit may concern: A Be it known that I, ADOLPHE IsIDoRE VAN VRIESLAND, acitizen' of Holland, .residing at, Paris, France, have invented certain new and useful Improvements i-n Carb ureter- Compressors, 4(for which I have obtained Letters '1897; -in England, No. 16,907, dated July 17,' 1897 in Austria, No.4 7 4, 553, dated November 4,1897 in Hungary, No. 10,445, dated A u gust 5, 1897-;` inv Belgium, No. 129,503, dated July 16, 1897; in Italy, No. 33, dated Septein ber 30,1897, and No. 45,386,'dated August 28, '1897; in Spain, No. 2l,282, datedv September 10,1897; in Switzerland, No. 14,710, dated July 16, l1897,'and in Luxemburg, No. 2,904,

Referring tothe drawings, l represents a vcylinder closed at its-two extremities and divided by-apartition A into two chambers, one

formed f0ur -;he1ical conduits, which-are pariallelfoneto the other and are indicated on the irawings'by the numbersl 2 8 4.A These condu'its are'coled around the drum. They may consistant tubes iixed by any suitable means .iipnnthedrumsor of small partitions ff, fixed u fpon theouterperiphery of thedruni. The iponduits formed by these.- partitions are subsequently closed by a shell or lamella Il, xed "upon them in' any suit-'able manner. The rs't [conduit starts from Athe righthand side,l 4ex-` ftends along the horizontal'diameter'of the "drum, and ascends, while being coiledupon ,the 'said drum, in order to pass behind the second conduit,which commences at the top of tlleidrum and extends along the vertical Adiameter thereof; These two conduits are l coiledrparallel oneto the'other and pass after ribs impart suicient-rigidity to the disk and i, prevent the saine from warping.l

:wardbehind; the third conduit, starting along' Uponthedrum thus mounted on the shaft are the horizontal diameter of the drum toward the left side. rlhe three parallel conduits continue io be coiled and pass behind the starting-point of the first conduit, and so on. The conduits, instead of starting llush with the drum, have each a slightly-projecting end, so that they debouch into the chamber outside the drum. The four conduits above inentioned are thus coiled parallel one to the other all over the drinn and have inclined convolutions, the inclination or dip of which may vary for each apparatus. As they reach the end of the drinn each conduit communicates, through another conduit extending along one of the radial axes of the drum, with a box or chamber I arranged in the center of the right end of the drum. 'lhe second conduit, for instance, is extended to the center by a radial conduit, and the third, fourth, and, lastly, the first conduits are similarly each prolonged by a radial conduit l/, 2, 3', and i'. These four radial conduits debouch at right angles to one another in a central box or chamber I, which-communicates through the hollow part .T of the shaft with the smaller chamber C of the cylinder. A stuling-box j prevents the larger and smaller chambers from communieating directly one with the other. rl`he larger chamber is provided with an opening or neck Il', upon which is screwed either a funnel K for feeding the liquid hydrocarbons or a cap or stopper 7.; to close the opening. Moreover, this chamber communicates with a valve L, which allows the atmospheric air to enter it. The valve may be regulated so as to only open when the depression in the chamber has reached a given limit. Obviously this valve is arranged so as to prevent the escape of the air or gas'contained in the chamber. It can only admit air in the apparatus. The second or smaller'chamber C communicates with an expansion valve M or apparatus of any suitable construction, which is connected to thel pipe supplying the earbureted air to the apparatus where it is to be utilized. At the lower part of this chamber is arranged a Valve N, enabling the smaller chamber to communicate with' the longer chamber and connected to a ball n, so that it can only be opened when the level of the liquid in the Asmaller' chamber has reached a certain height. The arrangementof the ball is such that the valve is closed before the level of the liquid has fallen below the communicating opening.

The operation of my apparatus is as follows: Hydrocarbon is poured into the longer chamber through the funnel K, so that the level of this liquid in such chamber may be suiiiciently high toallow the ends of the conduits to dip successively inthe hydrocarbon as they are rotating. A rotary motion being now imparted to the shaft D, the end of each ofthe conduits will dip in' turn into the hydrocarbon. For example, the tube l dips as it ro'- tates into the hydrocarbon, and a quantity of this liquid enters the conduit. When the end of the tube is withdrawn from the hydrocarbon, it accomplishes one revolution in the air contained in the chamber until it comes back again to dip a second time into thehydrocarbon. As the conduitis arranged in the form of a helical coil, it will successively contain liquid layers separated by layers of air, and owing to thc rotary motion these liquid layers thus separated by layers of air will move in the first conduit from the lett end of the apparatus to the right end thereol'. Ai'ter a number of turnsa given portion of the liquid or gas, having cnteredthc mouth of the first conduit, will pass through the lirstradial conduit into the central-chamber I. From this chamber the air and the hydrocarbon proceed to the smaller or compression chamber C oi' the cylinder, the surplus hydrocarbon sinks to the bottom, and the gas expands in this chamber. Now as the expansion valve or apparatus is regulated to a given pressure the gas,whieh is highly charged with hydrocarbon in conscq uence ot' its contact with the liquid, will not be able to escape until the pressure has reached a given degree, and as, on the other hand, the drum continues to rotate and that hence earbureted air enters the compression-chamber constantly this carburetcd air will become compressed, and as soon as the required pressure is reached it will escape through the expansion or pressure valve and enter the main where it is intended to be utilized, and the supply will soon become regular and continuous. It will be readily understood that the pressure attained in the compression-chamber is limited, such limit corresponding to the height of the various liquid convolntions contained in one of the conduits. The surplus hydrocarbon reaching the com pression-chamber sinks at the betteln of such chamber, asalready stated, and gradually raises` a'ball or float which opens the valve, and in consequence of the pressure exerted above the level of the hydrocarbon the latter' returnsl into the first chamber until the ball closes the valve. There is thus no other loss of hydrocarbon than that used to enrich the air, the hydrocarbon returning to its starting-point.

It is obvious that with regard to the air in the irst"charnber as the rotation continues and in consequence of the depression produced by this rotation the valve L israised and the atmospheric air enters the chamber.

In the above description four parallel conduits are indicated; but it is'obvious that a lesser or greater number of such conduits may be used.

Among the advantages of my improved compressor the following are worthy of mention:

First. The heat produced by the compressioncompensates that which is absorbed by the carburation insuch a manner that, contrary to the operation of many carbureters, no lowering of temperature occurs within the apparatus.

Second. v The liquid hydrocarbon moves 604,948 i s l continuously from the drum-chamber to .the smaller chamber. l

VThe carburetor andv compressor may be utilized as an air or gas compressor only, if desired,y the hydrocarbon being then replaced by water or by any other liquid having no action on gas and water. l

Having -thus described my invention, I

claim` as new anddesire to secure by Letters opening at one end into the drum-chamber Patentj i l 1. In acarbnreting and compressing apparatus,the combination with a cylinder divided. by a partition into two`ehambers, of a rotary drum mounted in one of said chambers, a

series of conduits 'helically Wound adjacent to each .other around said drum, a box arranged at the end of the drum, said conduits and at the other end into said box, a passage between said box and the second chamber, an air-inlet valve and a supply-opening in the drum-chamber, and a gas-outlet valve in the second chamber, and a valved passage connecting the lower part of said chambers for the return of the surplus hydrocarbon, substantially as set forth.

2. In a carbureting and compressing apparatus,the combination with a cylinder divided by a partition into two chambers', of a rotaryV passage-between said box and the second' chamber, an air-inlet valve and a supplyopening in the drum-'chamber and a gas-outlet valve in the second chamber, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two su`t scribl ing witnesses. f
